The Large Hadron Collider (LHC) was successfully commissioned in 2010 for proton-proton collisions with a 7 TeV centre-of-mass energy and is now delivering 13 TeV centre-of-mass proton collisions. The LHC is pushing the limits of human knowledge, enabling physicists to go beyond the Standard Model - the Higgs discovery was announced in 2012 - and the LHC has the potential to go on and help answer some of the key questions of our age: the existence, or not, of supersymmetry; the nature of dark matter; the existence of extra dimensions and studying the Higgs boson in more detail. To extend its discovery potential and significantly reduce statistical error, the LHC will need a major upgrade in the 2020s to increase its scientific output by at least a factor of five beyond its design value, this is known as High Luminosity LHC (HL-LHC). HL-LHC-UK is a proposal for a five year project known as HL-LHC-UK2, which will continue the success of HL-LHC-UK and LESS1 prototyping phases and from 1st April 2020 will deliver key series production hardware and key beam physics studies to HL-LHC including crab cavity cryomodules, coldboxes for cold powering, and beam diagnostics hardware as well as collimation studies. The project will receive inward investment into the UK via CERN to enable UK industry to deliver key components to the LHC. The overall HL-LHC-UK2 project aligns closely with UK, European and global strategies for accelerator and particle physics, where the complete exploitation of the machine is central and of highest priority. The 2017 UK accelerator strategy review states "Recommendation 9 - Maximise the scientific and industrial return on the significant, long- term UK investment in CERN by exploiting synergies across thematic areas, and industry involvement." and states "Due to commence operations in 2025, the Large Hadron Collider (LHC) high luminosity project (HL-LHC) is a high priority for both UK and CERN. Current UK contributions to the upgrade research and development include advanced collimators, crab cavities, beam instrumentation and cold-powering systems. Involvement in this project enables the UK to make high profile and important contributions to the LHC machine upgrade". The STFC 2016-2020 delivery plan states "Supporting UK leadership in the technical upgrades at CERN" is a top priority, and also "Developing opportunities to engage industry and other partners earlier in the development of technology solutions".The work will fund a significant number of STFC staff at the Daresbury Laboratory as well as several academics, PDRAs and PhD Students in 8 individual Universities across the two Accelerator Institutes.

大型强子对撞机 (LHC) 于 2010 年成功投入运行，可进行 7 TeV 质心质子碰撞，目前正在提供 13 TeV 质心质子碰撞。 LHC 正在突破人类知识的极限，使物理学家能够超越标准模型 - 希格斯粒子的发现于 2012 年宣布 - 并且 LHC 有潜力继续帮助回答我们这个时代的一些关键问题：存在，或不是超对称性；暗物质的性质；额外维度的存在并更详细地研究希格斯玻色子。为了扩大其发现潜力并显着减少统计误差，大型强子对撞机将需要在 2020 年代进行重大升级，使其科学产出比其设计值至少增加五倍，这被称为高光度大型强子对撞机（HL-LHC） 。 HL-LHC-UK 是一项名为 HL-LHC-UK2 的五年项目提案，该项目将延续 HL-LHC-UK 和 LESS1 原型设计阶段的成功，并从 2020 年 4 月 1 日起交付关键系列生产硬件和关键光束HL-LHC 的物理研究，包括蟹腔冷冻模块、冷动力冷箱、光束诊断硬件以及准直研究。该项目将通过欧洲核子研究组织（CERN）获得英国的对内投资，使英国工业界能够向大型强子对撞机提供关键部件。整个 HL-LHC-UK2 项目与英国、欧洲和全球加速器和粒子物理战略紧密结合，其中机器的完整开发是核心和最高优先级。 2017 年英国加速器战略审查指出“建议 9 - 通过利用跨主题领域和行业参与的协同效应，最大限度地提高英国对 CERN 的重大长期投资的科学和工业回报。”并指出“由于大型强子对撞机 (LHC) 高亮度项目 (HL-LHC) 将于 2025 年开始运营，因此是英国和 CERN 的高度优先事项。英国目前对升级研发的贡献包括先进的准直器、蟹腔、光束仪器和冷动力系统的参与使英国能够为大型强子对撞机机器的升级做出引人注目的重要贡献”。 STFC 2016-2020 年交付计划指出，“支持英国在 CERN 技术升级方面的领导地位”是首要任务，同时“创造机会让行业和其他合作伙伴尽早参与技术解决方案的开发”。这项工作将资助大量资金达斯伯里实验室的 STFC 工作人员数量以及两个加速器研究所的 8 所大学的几名学者、PDRA 和博士生。
